To all whcmit mag/concern:

Be it known that I Awxaxnna '1. Brown,

citizen of the United States, and resident of Syracuse, in the county of Onondaga and- New, York, have invented certain anism out of action and the winding mechan .lsm of another ribbon into act on whenever thatot-her ribbon ismoved into position for use at the printing-point and the first ribbon is moved out of such position; another object is automatically to reverse the travel of each ribbon; another object is to ,-mount spools on thefsame shafts and t wind any ribbon ofl'I-and on to\its spools indhpendently of the other spools and their ribbon; another object is to move both ribbons out of position to be struck by the type at the printingpoint and to kee them so in orderth'at the type may strike directformimeograph work; another object is to prevent the mixi of the inking'materials of two ribbons w ich cross each other adjacent'to the rintingibbonsin lines running 'widthwi'se of 'thoi Eibbons, this being merely the preferred method, however; other objects will appear hereinafter. To these ends, the invention consists of features of construction, arrangements and combinations of devices hereinafter described and more particularly pointed out in the appended claiins.

. The references 22, 23 mark eseapement 2 wheels loose on but geared to the shaft 19 by means of bevel pinions 24 on said wheels and bevel pinions 25 journaled on arms fast to the shaft 19. Ri id and movable .dogs 26, 27 coact with sair? wheels 22, 23, one sort of dogs being actuated by a gate 28 and the other set of do by another gate 29. Gertain of the rec shafts 6 are arranged with arms to actuate gate 28, certain other of said rock shafts are arranged to actuate gate 29,

.and yet certain other shafts operate both gates. The wheel 22 has half as as wheel 23.

Inasmuch as the fore mechanism forms the sub eot-matter of another a plication'for Letters Patent of the United states, filed May 6, 1904, Serial N 0. 206,661, its construction. and operation need not be herein further described.

many teeth going escapement In the referred form of the invention, which is t iat illustrated. in the accompanying drawings, the ribbon-spools are mounted by pairs upon two shafts, and each ribbon asses from a s 001 on one end (as the front end) of one'shait to a spool on the other end (as the rear end) of the other and adjustable oblique guides for each ribbon. are provided for guiding the ribbons from s 001 to spool, the adjustability of the gui es roviding for the shifting of the ribbons to ring one into and to put the other out of use at the printing-point, and also throwing both out of position when mimeograph done.

In the preferred form of the invention, the oblique guides for the ribbons are all rigidly connected together, so thatone movement will accomplish the shifting of one ribbon out of and the other into position for use; or both out of position when mimeographing is to be done. The oblique guides, in the preferred form of the invention, are disconnectably attached to a reciprocatory rod for the pur ose of usin the ribbon in transverse lines, wh' e the spools of the ribbon in use are intermittently rotated to draw the ribbon off of one and to wind it on the other of its spools, and the feeding mechanism of the ribbon not in use is out of action, whence it follows that each ribbon is used uniformly from end to end, as a subsequent use begins where the revious use left off.

The shaf ts on which thespools are mounted are rotatable and the spools are independently connectible with said shafts, whereby either spool on a shaft may be rotated thereby independently of the other spool, as in putting on a ribbon, and in the regular use, of the machine.

Where the ribbons, in passing from one spool to another, move in parallel paths and each ribbon is off-set from one ,to another of said paths by parallel oblique guides, the ribbons may be used in transverse lines by automatically moving said guides back and forth in the direction of the len th of-said ribbons, the part used being in t e offset, or path from one to another of said parallel paths;

but if there be no automatic reciprocation of said guides, and the ribbon be used in said off-set portion, longitudinal lines of the ribbon are used. If non-parallel oblique guides be used, the ribbon may be used in either transverse or longitudinal lines according as the guides are reciprocated or not. to say, that insofar as the changing of the ribbon in use by moving the guides is concerned, the automatic reciprocation of said guides is a secondary matter; though I prefer to have such automatic reciprocation, or to use the ribbon transversely.

Referring now to the drawin s, the reference numerals 30 31 mark two s afts mounted in the standards 2 for both rotation and That is i work is to be senses endwise motion. 32 marks the spools for a ribbon B, and 33, the spools for a ribbon it, said spools being loose on said shafts and independently connectible thereto by clutch members 34, which engage corres onding clutch members formed on the insid of the hubs of the spools, as indicated in Fig. 4. Each of the shafts 30 and 31 is extended through the framework towards the front of the machine, has fixed thereon a cranlr handle 34. The shaft may be connected-to either of the spools mounted thereon by moving said shaft endwise, and the ribbon may then be wound on that spool by turning the crank. The reference letter G designates the guide-plate as a whole (see Fig. 10), plate preferably being formed from a piece of sheet-metal cut and bent into the desired shape. At the front side of the guidelate G isa bar-35 to which eyes 36 are suitab y atta'ched by screws or rivets. Extending rearwardly from said bar at the right is an arm 37, from which extend the parallel oblique guides 38; while from the left hand end of bar 35, the arm 39 extends rearwardly and has the parallel oblique guides 40 extending therefromatright angles to the guides 38. For the purpose of mutual support and strength, the ends of guides 38 and 40 are joined by the parts 41, 42, and the rearmost guide 40 is set slightly above the plane of its companion by vertical shoulders or ofi-sets 43. If desired a transverse bar may be provided to support the end 42. For the pose 'of preventing the ribbons R and B rom rubbing against each other, he triangular U-shaped guide 45 is provid the ribbon R passing therethrough while the ribbon B passes thereover. Lugs 46 serve to retain the selvages of the ribbons in place. At the front of the bar 35 is theforwardly extending arm 47 which has a finger piece 48 turned up therefrom. 'The oblique guides 40 are of the sort sometimes designated in this art as turning bars.

A bar 49 extends across the machine and passes through the eyes 36 (see'Fig. 2), and said bar has three notches 50, 51, 52 cut in its forward side. The bar 35 of the guide plate G has a bell-lever 53 fulcrunied thereon at 54 (Fig. 2) and said lever 53 is provided with aringer-piece- 55 adjacent to the finger-piece 48 above mentioned, and also a tooth 56 which is adapted to enter the notches 50, 51, 52 and thus attach together the plate G and bar 49. is in the notch 56, as shown in Fig. 2. the

plate G is in such a position. that the ribbon 13 is in use at the printing-point. By pressing parts 48 and 55 together, the tooth 56 is disengaged from whate er of the notches 50 When the tooth 56 1 51 and 52 it may be in engagement with, and

the plate G may he slid along the rod 49. 1 I v w When tooth 56 is engaged with notch e1,'the ribbon R is brought into position for use at printisgepoint, while ribbon Bis-moved -7 is opposite the printing point, whereby the type strike .direct. for mimeograph work. A. spring 58 serves to keep the tooth 56 in engagement with the notches 50, 51, 52.

he rod 49 has an automatic .endwise mo tion so as to move the plate G to and fro and cause the ribbons'to be used Widthwise-thereof, each in the part thereof lying between its parallelohlique guides and where buta single thickness of the ribbon intervenes between the paper and the type. The mechanismsbown =1]! the drawings for giving the rod 49 its automatic endwise motion will now be described, reference being had first to Fig. 4.

The sprin drum 16 has fast thereto a plate 59 which as a flange 60 on which is wound the strap 17. Mounted'loosely on the hub 61 of the late 59 is a cam-plate 62 provided with rate et teeth 63 on its peri hery. The

hub 61 turns on the shaft 64 to w ich one end of the spring 65 is fast, said shaft 64 being journaled in the plates 66 and rovided with a ratchet and pawl 67 as usua Pivotcd to the plate 59 is a pawl 68 (see Figs. 6- and 11) which is held inengagement with ratchet 63 by a spring 69, the parts being so arranged that the pawl drives the ratchet during the forward movement of the paper carriage. The cam plate 62 has formed in its front face a cam oove. 62,- in which works a follower consisting of a roller or pin 70 which is carried by a oke-shapecl frame -71.- This frame stradd es the spools 32 and 33, and one i of its arms is fulcrumed on a sleeve72 which is fixed to a plate 66 and which forms the bearing for. one end of the shaft 31. The other arm of the frame 71 is j ournaled on the shaft 31 itself, 'ust inside the front post 2 lines.-

(see F' 4). e cam groove 62 im arts to the ame 71 anoscillatory'motion a out the shaft 31. The shaft 30 has journaled thereon a frame 73, similar to the frame 71, each of said frames 71 and 73 being shaped somewhat like aninverte'd U. The transverse parts of these frames form guides for the ribbons B and R. The bar 49 is pivotallyconnected at its ends with the frames 71 and 73 (Figls. 2 and 6). The cam 62 reciprocates. t e frames 71 and 73, the bar 49, and the guide plate-G, whereby the ribbon in use at the printing oint is moved widthwise during the forwar movement of the carriage'. The above described mechanism moves the bar 49 to and fro-endwise and ink is taken from the ribbon in use in transverse For the purpose of-feeding the ribbon in use, the following mechanism is rovided in the machine illustrated in the rawings: Friction springs 7 4, (Figs. 1 and 6), fast on the frames 71, and 73,?bear against the spools 32, 33, and bause them to move in unison with the said frames, except as hereinafter mentioned. Each spool is provided with a ratchet wheel 75, the ratchet wheels of the spools being, by reference, on the ends ad jacent to each t er. Pawls 76 are hung at 7 on the main rame of the machine and are adapted, when in Working positions, to coact with said wheels 75 to revent the corres onding spools from eing oscillated wit the frames 71 and 73 by the frictional contact of the springs 74,-the pawl permit ting the spool to turn only in one direction.

When one of the pawis 76 is in engagement with the ratchet wheel of one of the spools, the-corresponding friction spring 74 turns that s ool in one direction, but rubs idly over it in t e other, with the result that the ribhon is fed longitudinally. This operation re quires that the other spool of that ribbon be not restrained by its pawl 76. To this end,

throw -outs 78 are provided consisting of V levers pivoted on the shafts 30, 31, and hav ing cam ends adapted to co-a with and raise the pawls as indicated in lg 1,7 by the full lines. The throw-outs 7 8 for'tln'e spools 32 are connected by a link 79 and the throwouts 78 for the spools 83 are connected by a link 80, the connections in each case being such as to move one throw-out into working position 'as the opposite throw out. is moved out of working position. Spring-actuated pins 81, seated in holes in the side pieces of the main frame, co act with notches 82 in one of each pair of throw-outs 78. to hold the latter in position. v

In Figs. 7 and 9 are shown the two spools 32 which carry the ribbon B, with the res versing mechanism setto feed the ribbon towards the spool shown in Fig. 9.

One of the throw-out levers 78 of each pair is formed with a handle portion 78 whereby the feed of either ribbon may be reversed by hand. I have also provided automatic mechanism for operating the throw-outs 78 to reverse the endwise travel of the ribbon. Rods 83 and 84 are fixed in the frames 73 and 71 respectively, each of said rods extending above the spools from one arm to the other of its frame. Arms 85 are loosely hung on the rods 83 and 84, and said arms have curved free ends which rest on the ribbons wound on the several spools. The barrels of the spools are slotted at 86 to allow the ends of the arms to drop into the barrels when the ribbons uncover said slots, as indicated in Fig. 7. Each arm 85 has a second arm 87'integral therewith, which second arm is adapted, when arms 85 drop into slots 86, to drop behind a shoulder 88 on the corresponding throw-out 78, which at such time is in operative position to hold the corresponding pawl 76 out of action (as indicated in full lines in Fig.7). At the next oscillation of the frame 71 or 73, this 4 chine illustrated in the drawing, such slidingslide endwise.

arm 87, pressing against the shoulder;88, moves the. throw-out lever 78 so that the Corresponding pawl 76 will be allowed to drop into engagement with the corres 0nding ratchet wheels 75, (as indicated by otted lines in Fig. 7).- As aboye stated, the o posite throw-out is also moved but in t e opg osite sense; thus, the throw-out 78 shown in ig. 7 holds its pawl 76 out of action while the throw-out 78 shown in Fig. 9 allows its pawl 76 to act; these two throw-outs 78-are connected by the rod 80, and when the left hand one (Fig. 7) is'moved to allow its pawl 76 to drop into engagement with the ratchet wheel, the right hand one (Fig. 6) is moved to the left and raises its pawl 76 out of engagement with the ratchet wheel 75.

For the purpose of rendering inoperative the feeding-mechanism of the ribbon not in use, the machine illustrated in the drawing is provided with .the"'-following devices Each pawl 76 has an arm 89 extending upward beyond its pivot, and two slidable bars 90, 91 are provided, which have cam notches 92 therein. arranged to coact with the extensions 89 of the pawls 76. When a notch92 is opposite an extension 89 and the throw-out 78 corresponding to that extension allows the pawl to drop into engagement with the correspondin ratchet wheel, then that pawl may so drop; ut'if the bar 90 o1$91 be moved so as to rock the pawl on its pivot, then that pawl may not engage with the ratchetwheel,

no matter what may. be the position of its throw-out 78. By sliding the bars 90, 91

endwise, their notches 92 may always be kept opposite the extensions 89 of the pawls 76 for the ribbon in use at the printing-point and the awls 76 for the ribbon not in use may be eld out of operation. In the maof the bars 90, 91 is made automatic by the following means :-'A- bar 93 (Fig. 2) is provided with slots 94 through which pass screws 95 which secure said bar to the topplate or type-ring 3, whereby said bar 93 may These screws also pass through slots in the forward ends of bars 90 and 91, and similar screws pass through" similar slots in the other ends of said bars, which are thus guided to slide in a front and back direction. The bar 93 is provided with cam-slots 96 into which pins 97 on the bars 90, 91 project as shown. Endwise motion of bar 93 thus causes endwise motion of the bars 90, 91, but the bars 90, 91 move in opposite directions on account of the arrangement of the cam slots 96; The bar 93 has two shoulders 98, 99thereon in .position to be struck by the guidelate G, whereby the bar 93 is moved in one direction or the other, as follows :When it is desired to use the ribbon B at the printing point, the plate G is moved along rod 49 until tooth 56 enters notch 50. If the cam 62 is in such a. position that the frames 71 and'73 occupy the positions shown in Fig. 2 the late G, engaging the shoulder '99, moves't e bar 93 to the position thereof shown 111 Fig. 2; or, if the cam is not in such position,'the bar 93 will be shifted when the cam reaches that osition in the'operation of the machine. f the plate'G be 'moved to the left to bring tooth 56into notch 51, and cam 62-be turned to move frames 71 and 73 to .their extreme left-hand positions, the plate G strikes shoulder 98 and moves the bar 93 to the left.

'In the first case, the'bar 90 is slid rearward and bar 91 is slid forward, assuming that they do not occupythe positions shown in Fig. 2 while in the second case, bar 90 is slid forward and bar 91 is slid rearward from the positions shown in Fig. 2'. a

The arrangement of the various devices and mechanisms, (the adjustable guide-plate G, the'ribbon-feeding mechanisms, the mech-.

anism for throwing either ribbon-feed out of operation, etc.) is such that only the ribbon in use is fed endwise while the ribbon not in use remains substantially where it was when thrown out of use until again brought into use, so that such new use begins substantially where the previoususe left off, while any ribbon may be removed and be replaced by a new one without moving or disturbing the other ribbon.

,In addition to the foregoing, the plate G may be so located that neither'ribbon is inuse at the printing point. This may be secured in either of two ways, one by having the notches 50 and 51 so far a art and the space 57 so long that the gui -plate may reciprocate while mimeograph work isbeing done without moving either ribbon where a type can strike it, and the other by setting e'plate G, with tooth 56 in notch 52, disconnecting the rod 49 or some part of its driving-mechanism, and fixing said-rod 49 in a mid-position with space 57 at the printingpoint. .One means for securing this latter result is shown in the drawing (Fig. 11). A

slide 100,-mounted on the disk 59, is adapted to engage with a tail. 101 on the pawl 68 and disengage said pawl from the ratchet-wheel 63. Said slide-'bar100 is slotted and engages with the screw-by which the pawl 68 is se. cured to the disk 59; it also has a wedgeended flange 102whichengages with the tail 101, and a forwardly extending arm 103, by which it may be slid on said screw, and a guide-piece 104 secured to the disk 59. When pawl 68 is moved into the position shown by dotted lines in Fig. 11, the cam 62 is not moved thereafter by the s ring-drum, and the rod 49 and frames 71 an 73 may be moved to a position such that space 57 is opposite the printing-point, the cam 62 being turned by hand as necessary to secure such result.

From the foregoing description, it is evispecified which fall I seeped dent that, while the construction shown is a convenient and ready means for carrying the invention into effect, the invention 18 by no means limited to such a construction- The invention is to be understood, therefore, as. embracing all means for effecting the result within the spirit and sco e of the claims appended hereunto.
